Why does sodium chloride change colour when heated?
As sodium chloride is heated, the vibrations of the individual sodium chloride molecules increase, forcing adjacent sodium chloride molecules to move away until they have enough room to vibrate. Once the temperature increases to 801 °C (1,474 °F), the molecules are so far apart that they can't hold together anymore. So, they fall apart and act as a liquid. Viola, molten sodium chloride.
How can you alter sulfur to make it conduct electricity?
no because it is not a metal and is not electro-positive.
What pH is a soultion of sodium chloride in pure water?
it has neither an acidic nor an alkaline pH, it is neutral at pH 7
Sodium chloride crystals can be cube shaped?
Yes, sodium chloride crystals can form cube-shaped structures due to the arrangement of sodium and chloride ions in a repeating pattern known as a face-centered cubic lattice. This cubic shape is a result of the strong ionic bonds between sodium and chlorine atoms in the crystal lattice.
What happens when sodium chloride solution and carbon dioxide is mixed with spaghetti?
When sodium chloride solution is mixed with carbon dioxide and spaghetti, a small amount of carbonic acid may form due to the reaction between carbon dioxide and water. This may slightly alter the taste of the spaghetti. However, the overall impact on the spaghetti would be minimal.
What does salt water do to bonds?
Salt water can disrupt ionic and hydrogen bonds between molecules. When salt (sodium chloride) dissolves in water, it dissociates into sodium and chloride ions, which can interfere with the interactions between other molecules, such as proteins and nucleic acids. This disruption can affect the structure and function of these molecules, leading to changes in biological processes. Additionally, the presence of salt can alter the solubility and stability of various compounds in solution.
Is Lithium chloride aqueous solution acidic or basic?
Lithium chloride aqueous solution is neutral. It will not significantly alter the pH of the solution.
Can calcium chloride be substituted for pickling salt?
Calcium chloride can be used as a substitute for pickling salt, but it may alter the flavor and texture of the pickled product. Pickling salt is pure salt (sodium chloride) without additives, which helps in preserving the crispness of vegetables. Calcium chloride, often used to enhance firmness, does not provide the same flavor profile and may result in a different taste experience. If using calcium chloride, it's best to adjust the quantities and be prepared for a variation in the final product.
2 Why is it wrong to leave a bottle of anhydrous sodium sulphate or calcium chloride open?
Leaving a bottle of anhydrous sodium sulfate or calcium chloride open can cause them to absorb water from the air, making them less effective in their intended use as drying agents. This can alter the concentration and properties of the chemicals, leading to inaccurate results in experiments or processes that require precise conditions.
What color is pasta when copper sulphate and sodium chloride is mixed with it?
The copper sulphate will likely give the pasta a blue or green hue, while the sodium chloride (salt) will not significantly alter its color. The overall color may appear bluish-green due to the copper sulphate.
What is the most electricity you can make with a magnet coil?
A coil doesn't make electricity it can however alter voltage and amperage output.
When a pellet of sodium is sliced in half is that a physical or chemical change?
Slicing a pellet of sodium in half is a physical change because it does not alter the chemical composition of the sodium. The sodium is still sodium before and after slicing, just in smaller pieces.
